In order to successfully pick a locked chest, One must first get all the pins set in the position in which a working key would hold them. To do this, start by having the head of the pick hovering over an unset pin. Left click on your mouse to push down the pick which will subsequently push down on the pin under. When the pin STARTS to rattle and you here a rattling sound you are at the point in which it will be set by releasing the left mouse button. Release immediately when this occurs, if the push is continued, the lock pick will break. It is a good idea to plan on using 2 attempts per pin because the pin will set immediately BEFORE it starts to rattle. The point at which the pin will set is often passed by on the first attempt. Time being an issue, the advisable choice would be to start at one end of the row of springs and set them consecutively. For practice listen and watch the pin for one push, Remember the level the top of the pin is at when the rattle begins. Let go Immediately. If it does not remain on that level(set) push again ready to release right before it begins to rattle. Try noticing the spring, It may help indicate the right level as well. Right clicking instead of releasing the left click will also stop the push of the pick. Right clicking seems to have a quicker reaction time and is most likely preferable.
